Thanks for your work tracking this one down.

It's a shame this was so hard to figure out --- I wonder if there's
some temperature sensor the kernel could use to help diagnose this
kind of thing.  If some day you come up with some possible improvement
to the kernel in that vein, please feel free to contact
linux-kernel@vger.kernel.org about it (cc-ing me if you want).
